By the way, in the above ice sphere manufacturing apparatus, the ice spheres formed in the Freon liquid as the cooling medium are placed in the water as the separation medium located in the upper layer of the Freon liquid. The water should be kept at or near 0 ° C. so that it does not bind to each other into a lump and to prevent ice balls from melting in the water as much as possible. Therefore, as a means to deal with these problems,
In the ice ball manufacturing apparatus described above, a heater, a stirrer, and a temperature control device are provided to precisely control the temperature of water as a separation medium. For this reason, the apparatus becomes complicated and large-sized and expensive, and since the water as the separation medium is at 0 ° C. or close to it, the ice balls in the water are further frozen or melted to form ice balls. It is unavoidable to present a lumpy state that binds to each other. Therefore, it is an object of the present invention to address such issues.

As described above, in the ice ball manufacturing apparatus according to the present invention, mercury having a large specific gravity (specific gravity 13.
Since 5 g / cm 3 ) is adopted, the ice balls solidified in the cooling medium are hard and have a fine grain. Further, since the salt aqueous solution is used as the separation medium in the upper layer of the cooling medium, the ice balls in the cooling medium can be smoothly transferred into the separation medium and can be easily separated from the cooling medium. Also,
The separation medium is a salt solution and the melting point of the solution is below the melting point of ice, so the ice balls do not melt, and the separation medium freezes at the boundary between both media or the entire separation medium freezes. Therefore, it is not necessary to attach a heater for preventing freezing and to provide a temperature control device for precise temperature control as in the case of using water as a separation medium. Since the separation medium has a smaller thermal conductivity than mercury, which is a cooling medium, heat transfer between the outside and the cooling medium is prevented, and energy loss is prevented.
